  By the way, in a conventional headset system that realizes a hands-free call by performing voice communication conforming to the above-described Bluetooth standard, only one type of ring tone can be output at the time of an incoming call. Therefore, it is desired to develop a headset system that can change the ringtone according to the caller.

  Here, in the mobile phone terminal, as the memory capacity increases, it is possible to store a plurality of types of audio data in the memory. Therefore, in the headset system, in order to output a plurality of types of ringtones from the headset, a plurality of types of voice data are stored in the mobile phone terminal, and the voice data selected for each caller is stored in the headset. By establishing a voice link for transmission, it is considered possible to output a different ringtone for each caller from the headset.

  However, the method of establishing a voice link requires a very large amount of power because it is necessary to transmit voice data from the mobile phone terminal to the headset every time there is an incoming call. This leads to a problem that the usable time of the machine is shortened.

  The present invention has been made in view of such circumstances, and provides a headset system capable of outputting different ringtones from a headset according to a caller with low power consumption. Objective.

  A headset system according to the present invention that achieves the above-described object is a headset that is attached to a body of a mobile phone terminal and a user of the mobile phone terminal and performs voice communication with the mobile phone terminal. The mobile phone terminal has communication means for transmitting data related to the caller of the incoming call to the headset, the headset corresponding to the caller as a ring tone Storage means for storing a plurality of types of audio data designated to be output, and a plurality of types of audio data stored in the storage means based on data relating to the caller received from the mobile phone terminal And a ringtone output means for outputting a ringtone composed of voice data selected from among them.

  In such a headset system according to the present invention, the mobile phone terminal does not transmit different audio data for each caller to the headset, but the caller has a significantly smaller data size than the audio data. Is transmitted, and based on this data, audio data that is alternatively selected from a plurality of types of audio data stored in the storage means of the headset is output. Therefore, in the headset system according to the present invention, it is possible to suppress power consumption of the mobile phone terminal, prevent a reduction in usable time of the mobile phone terminal, and to receive a plurality of types of incoming calls from the headset. Sound can be output.

  According to the present invention, it is possible to output different ringtones from the headset according to the caller with low power consumption.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  As shown in FIG. 1, the headset system shown as an embodiment of the present invention includes a mobile phone terminal 10 and a headset 20 that is worn on the body of a user of the mobile phone terminal 10.

  The cellular phone terminal 10 includes a Bluetooth module 11 that performs voice communication based on a communication method compliant with a so-called Bluetooth (registered trademark) standard. Here, Bluetooth is a communication method that has a longer communication distance and stronger resistance to obstacles than infrared communication, and it is necessary to set the devices so that they have a straight line-of-sight positional relationship like infrared communication. There is no communication method. On the other hand, infrared communication is a communication method capable of transmitting and receiving signals with lower power consumption than communication based on the Bluetooth standard.

  On the other hand, the headset 20 is configured to be able to perform voice communication with the mobile phone terminal 10, and corresponds to the mobile phone terminal 10 and performs voice communication based on a communication method compliant with the Bluetooth standard. A Bluetooth module 21 for performing

  In such a headset system including the mobile phone terminal 10 and the headset 20, during a call, audio is transmitted between the mobile phone terminal 10 and the headset 20 based on a communication method compliant with the Bluetooth standard. Communicate. That is, the headset 20 establishes a communication path between the Bluetooth modules 11 and 21 in the case of a call mode by the mobile phone terminal 10, and the mobile phone terminal 10 based on a communication method compliant with the Bluetooth standard. The voice received by the user is received and outputted to the user via headphones or earphones, and the voice spoken by the user is captured via a microphone or the like to the mobile phone terminal 10 Send.

  Here, the headset 20 stores, in a memory (not shown), a plurality of types of voice data designated to be output as ringtones in correspondence with the caller, and the caller received from the mobile phone terminal 10 The user can listen to ringtones consisting of audio data selected from multiple types of audio data stored in the memory based on the data related to the sound via the ringtone output means such as headphones or earphones. Output to. At this time, the cellular phone terminal 10 and the headset 20 transmit and receive data regarding the caller via the Bluetooth modules 11 and 21.

  Specifically, in a headset system, a so-called AT command for performing call control of a mobile device from an external device using a so-called ACL (Asynchronous Connection Less link) channel defined by the Bluetooth standard. Is transmitted / received between the mobile phone terminal 10 and the headset 20, data related to the caller of the incoming call can be transmitted / received. Here, since the data relating to the caller consists of an AT command and a result code corresponding to the AT command, the data size is significantly smaller than that of voice data, and transmission / reception can be performed with extremely small power.

  In this case, the headset 20 performs ring tone output control according to a series of procedures as shown in FIG. Here, for convenience of explanation, when two types of voice data A and B used as ringtones corresponding to each of the first telephone number and the second telephone number are stored in the memory of the headset 20 Will be described.

  First, as shown in the figure, the headset 20 establishes an ACL link by handshaking with the Bluetooth module 11 of the mobile phone terminal 10 via the Bluetooth module 21 in step S1, thereby establishing a mobile phone terminal. Shift to a state in which data can be transmitted to and received from the machine 10.

  Subsequently, the headset 20 transmits a command of AT + CLIP = 1 to the mobile phone terminal 10 via the Bluetooth module 21 in step S2. Here, the + CLIP command is used for setting display of a caller telephone number that is being received. The headset 20 transmits the command of AT + CLIP = 1 to the mobile phone terminal 10, and when an incoming call is received, the caller's telephone number is set as the unsolicited result code + CLIP corresponding to the command. It can be set to be notified from the mobile phone terminal 10. Note that the unsolicited result code is different from the result code that is answered each time an AT command is input, and when the mobile phone terminal 10 receives an incoming call or when the state of the mobile phone terminal 10 changes. The result code is automatically transmitted to the headset 20. As described above, the headset 20 receives a notification when an incoming call is received by the mobile phone terminal 10 by transmitting a command of AT + CLIP = 1 to the mobile phone terminal 10 in advance. It becomes possible.

  When the mobile phone terminal 10 receives an incoming call, the headset 20 receives the unsolicited result code RING + CLIP transmitted from the mobile phone terminal 10 via the Bluetooth module 21 in step S3. . Here, the unsolicited result code RING is a notification that an incoming call has been received as a response to the above-mentioned command of AT + CLIP = 1, and the telephone number of the caller, whether this telephone number is an international number or a domestic number It contains information such as the type. The headset 20 can identify the caller's telephone number based on the received unsolicited result code RING + CLIP.

  When the headset 20 identifies the caller's telephone number in this manner, if the identified telephone number is the first telephone number in step S4, the headset 20 stores the 2 in the memory in step S5. Of the types of voice data, the voice data A corresponding to the first telephone number is selected, and this is output as a ring tone. On the other hand, if the identified telephone number is the second telephone number in step S4, the headset 20 selects the second type of audio data stored in the memory in step S6. Audio data B corresponding to the telephone number is selected and output as a ringtone. In step S4, if the specified telephone number is neither the first telephone number nor the second telephone number, the headset 20 generates a ring tone based on predetermined voice data set in advance. Output, and the series of processing ends.

  As described above, in the headset system shown as the embodiment of the present invention, the mobile phone terminal 10 does not transmit different audio data for each caller to the headset 20, but rather than the audio data. Data relating to a caller having a significantly smaller size is transmitted, and based on this data, audio data selected from a plurality of types of audio data stored in the memory of the headset 20 is output. Thereby, in this headset system, the power consumption of the mobile phone terminal 10 can be suppressed, and shortening of the usable time of the mobile phone terminal 10 can be prevented. Therefore, in this headset system, different ringtones can be output from the headset 20 according to the caller with low power consumption.

  The present invention is not limited to the embodiment described above. For example, in the above-described embodiment, the communication method conforming to the Bluetooth standard is used. However, the present invention can be applied when any communication method is used regardless of the type of wired or wireless. .

  Thus, it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.

It is a figure which shows the structure of the headset system shown as embodiment of this invention. It is a flowchart which shows a series of procedures at the time of performing output control of a ringtone in the headset in the headset system shown as embodiment of this invention.
